SPEGIFIGATIQN forming part of Letters Patent No. 726,713, dated April 28, 19(53. Applicstionfll edDecember11,1902. Seriallllo-154,863. (roman) To all whom it may concern.

Be it known that I, BRUNO LIMBERG, a subject of the German Emperor, residing atKeL' sterbach-on-the-Main, Germany, have in vented certain new and useful Improvements in Wagon-Unloading Devices, of which the following is aspecification.

Thesubject of the present inventionis an unloading device forgoods-wagons, in which the floor of the wagon is removed in a known manner from the wagon-frame, raised, and can be either tilted toward the four sides or can be raised horizontally. In distinction from the already-known devices of this kind the subject of the present invention possesses the characteristic that the devices serving to raise the wagon-door are arranged outside the wagon-frame and below the floor and the loading surface in suitable positions, by which means a reduction of the loading-surface on account of the raising devices is obviated, but at the same time an overstepping of the usual width of the track in the unloading and normal positionsis avoided.

In the accompanying drawing, which shows tion is applied, a is a cross-beam of the underframe of the wagon, 7) is the front side of the wagon, and f the longitudinal side thereof, which can be, opened out upward in such a way that when turned into their highest position they cannot automatically fallback again. On the crossbeazns a and upon the longitudinal carriers 2 of the underframe the floor 0 lies free. This door for thesake of strengthening it can be surrounded with a frame of angle-iron. ()n the longitudinal other devices, each pair of which may adverb tageously be operated by a common crank on a shaft carrying pinions engaging the racks, as indicated in dotted lines. By a simultaneous turning-of the cranks on both sides of the wagon the doors will be raised, lying horizontal. If, however, only the gearon one side of the wagon is actuated, the door assuxnes a canted position in one of four directions, as shown in dotted lines, so that the contents of the wagon are caused to slide, and the wagonis quickly unloaded. i

An important point is that no portion of the floor c, in whatever position it may be, protrudes beyond the general outline of the car, as indicated by the dotted line 9, This makes it possible to discharge the contents of a car standing on one track onto a neighboring track without causing any risk to passing trains by reason of the protrusion of any part of said car into the path of said trains.

What I claim, and desire to secure by Let-- ters Patent of the United States, is

l. A wagon or car having a stifi floor entirelycovering its bottom, and mechanism for tilting the floor as a whole, sidewise or endwise, substantially as described.

2. A car having a stiff floor entirely cover ing its bottom and rack devices at the corners arranged to move the door as awholeto discharge the contents in any direction; substantially as described.

In testimony whereof'l have hereunto set my hand in the presence of two witnesses.
